Title: Lubricating structure of positioning part of injection mold
Inventor: MATSUOKA TAKESHI
IPC: B29C45/83
Filed: 1986-06-27
Abstract: PURPOSE:To prevent rusting from generating and consequently suppress the generation of defective molding such as burring, ununiform wall thickness and the like of a molded item by a method wherein recesses are bored at a tapered positioning part, at which the fixed mold and movable mold of an injection mold abut against each other, in order to house lubricant therein. CONSTITUTION:By moving a movable mold 3 toward a fixed mold 2 side, both the molds are abutted against each other. The positioning parts 21a and 22a and 31a and 32a of both the molds 2 and 3 are brought into surface contact with each other for mold registration. Under the state just mentioned above, molding resin is injected from a sprue 4 into cavities A and B so as to mold a resin molded item. After molding, the movable mold 3 is separated from the fixed mold 2 and the resin molded item is removed from the molds by ejecting an ejector rod 6. Because solid lubricant G housed in recesses 21b and 22b and 31b and 32b forms favorable lubricant films, wear is reduced and rusting can be prevented from generating. In addition, the generation of gap becomes difficult and the generation of off-setting is suppressed and consequently the generation of defective molding such as burring, ununiform wall thickness and the like of a molded item is suppressed.

Title: Semiconductor memory device
Inventor: HIDAKA HIDETO
IPC: G11C11/34
Filed: 1985-07-10
Abstract: PURPOSE:To prevent a non-selected word from floating up during recharging a bit line potential by giving a potential change in a negative direction only with respect to the non-selected word line during the recharging. CONSTITUTION:A new control signal phi1 rises to an L level at the start time (time t4) of a recharge cycle and to an H level at the time t5 on the completion of the recharging. At the time t3, when a word line WL0 is selected and other word line WL1... are non-selected, that is, at an earth potential level, an electrode opposing to the gate of a MOS capacitor C0 remains H level and other electrode opposing to the gate of a MOS capacitor C1 becomes the earth potential. Accordingly, during recharging (time t4-t5), a negative coupling is given only to the non-selected word line and a coupling noise in a positive direction due to the raise of the bit line potential during recharging is canceled.
